With the Fast disruption in mobile networks in India i.e. from 2G to 5G in a very short span, with this the Network operators are really in trouble to quickly shape their infrastructure to the latest technologies. In this process most of their infrastructure and their heavily invested network lease becomes NPA’s.(Non Performing assets) .
On the other hand there IoT is emerging, the rapidly-transforming IoT connectivity landscape is poised for another major shift.
While Most IoT applications can vary greatly,
- but many applications need tons of sensors spread over big areas.
- When we have thousands of sensors spread over a big area, you need wireless communication with long-range and low power consumption, it’s a
- the tremendous operational burden to replace the batteries in thousands of sensors on a frequent basis.
LPWAN technology thus plays a crucial role in enabling the Internet of Things. These networks make it possible to have many thousands of sensors/devices collecting and sending data at lower cost, over longer range, and with better battery life than other connectivity options.
While most of the network operators are looking forward to Establish already developed LPWAN networks using their NPA’s so that they could make bucks out this boom with out large investments. NB-IOT, SIGFOX, LoRa,LTE-M are some very popular LPWAN Technologies that most network operators are preferring to choose.
Narrowband -Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new
IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency,
especially in deep coverage. Battery life of more than 10 years can be supported for a wide range of use cases.
Supported by all major mobile equipment, chipset and module manufacturers, NB-IoT can co-exist with 2G, 3G, mobile networks.
Has only one disadvantage, i.e since the network is on the Liscenced band the Cost increases.
Though Sigfox is on unliscenced band,is uplink only,so it won’t work for a large number of use cases currently.
LoRa Network is specifically developed to solve the LPWAN’s need with existing cellular infrastructure,
And a strong Protocol stack developed by a large community is another plus point.
According to the LoRa Alliance, 83 public network operators in 49 countries are using LoRaWAN today, with many more private enterprise networks running on LoRaWAN as well.
GSMA, the organization representing the interests of NB-IoT, LTE, and other mobile networks, claims that 40 countries are expected to roll out NB-IoT networks in the near future.
The LoRaWAN protocol allows data to be sent asynchronously, meaning data is only sent when necessary. This extends battery life of sensor devices in the field by as much as 10 years, keeping battery replacement costs low.
NB-IoT maintains a synchronous connection to the cellular network regardless if there is data present to send. This consumes considerable battery life for sensor devices, resulting in high battery replacement costs, which can be cost prohibitive in many applications.
LoRaWAN can support mobile sensors and track them as assets move from one location to another. This can be done even without GPS with good enough accuracy for many applications.
NB-IoT is limited to idle mode cell reselection today which is not well optimized for mobile asset tracking.
Another important reason I personally feel is because of the ability to make completely private network and make clients feel secure about their data.
India has itself witnessed large investments in few years. While Airtel has taken chance on NB-IoT,and TCL invested largely on LoRaWAN.
